There used to be a Toolserver tool that generates a list of potentially duplicated images between a local site and the repository (Commons) site based on the match of hash values derived from the image bytes. We would like to get the function of the tool restored, either by re-launching the code or reimplementing it.
Original task description:
https://toolserver.org/~multichill/nowcommons.php?language=it&page=2&filter= is no longer available
Is there another URL yet?
